Coat a non-stick skillet with cooking spray or a little bit of olive oil and heat over medium-high heat. When pan is hot enough, add onions and bell pepper and saute for about 30 seconds to a minute, just to soften them up a bit.
Add shrimp and saute until they start to turn pink but remain slightly translucent. Throw in pineapple, snow peas and green onions and continue cooking for about one minute.
Add ginger, sambal oelek and soy sauce and continue cooking for another minute or two to allow the flavors to combine.
Transfer to serving plate and garnish with sesame seeds.
Serve with raw bean sprouts. (if you prefer to cook your sprouts, stir them in at the very end and and cook for a few seconds only, so that they retain a little bit of a crunch)
